A man has been shot dead outside a tube station in north-west London, Scotland Yard has said.

The Metropolitan police were called to Cumberland Road outside Queensbury tube station at 9pm on Tuesday following reports of a shooting. A man in his 30s was found with critical injuries and he died at the scene almost an hour later.

Another man, in his 20s, was taken to hospital in north London with a gunshot wound and was said to be in a stable condition.

The Met is examining CCTV footage and has called for anyone with information to come forward.

DI Justin Howick said: “I would like to appeal to anyone with information to contact police at the earliest opportunity. Detectives are busy at the scene and working to build a clear picture of the circumstances of this fatal attack.”

A crime scene remains in place in Cumberland Road and in Essolado Way, the police said.

The death brings the total number of suspected murders in the capital so far this year to 63, prompting fears that violent crime could rise to the highest levels for a decade.

Last month the then home secretary, Amber Rudd, launched a serious violence strategy to clamp down on violent crime, which has been rising since 2014.

The strategy will be backed by £40m of Home Office funding and an offensive weapons bill to ban the sale of corrosive liquids to under-18s and introduce tougher restrictions for buying knives online. It will focus heavily on the links between illegal drug markets, particularly for crack cocaine, and violent crime.
